(Cl. 5216) ABSTRACT OF THE DISCLOSURE I Multi-purpose cantilever roof structure formed by an elongated bridge member which has pivoted side trusses projecin-g therefrom and which is supported in an erected state by telescopic load-bearing end-support legs provided on the bridge member, the trusses being collapsible against the bridge member, and the bridge member being mountable on vehicle bogies for transportation.

This invention relates to multipurpose cantilever roof structures, and is concerned with a collapsible transportable cantilever roof structure erectible to form a multipurpose shelter for use on temporary sites. Such a shelter is suitable for use as an amusement bump car hall, a pavilion, or a garage and parking hall for motor vehicles or the like.

Shelters formed of a vertical supporting wall with a shelter roof cantilevered therefrom are known for the accommodation of motor vehicles. It has been proposed that such shelters be further developed for use as shelters for market, exhibition or entertainment purposes, by constructing the vertical supporting wall for the cantilever shelter roof as a mobile frame. Furthermore, in order to facilitate the transport of such shelters, it has also been proposed that the cantilever roof be multiply subdivided into individual wing-like roof sections, and for these to be adapted to be swung-in, drawn-in or folded-up by means of the mobile supporting wall.

However such known shelters have the disadvantages of a relatively small covered surface area and the supporting wall often constitutes an obstacle when an outwardly foldable shelter roof is provided at both sides of the supporting wall, in that the covered areas are separated from one another by the supporting wall. Also known shelter constructions do not permit the provision of a freely supported roof which is necessary when a shelter is to be used for the aforesaid purposes.

It is an object of the present invention to provide a roof structure erectible to form a multipurpose shelter for use as an amusement bump car hall, a pavilion, or a garage and parking hall for motor vehicles or the like, which shelter has a maximum covered surface area unimpeded by intermediate walls, props or supporting posts, the roof structure being capable of erection by a few people in a very short time and being transportable as a single unit in a non-erected state.

Accordingly the present invention provides a multipurpose cantilever roof structure including an elongated bridge member, hydraulically operable load-bearing telescopic end-support legs on said bridge member, a plurality of side trusses pivoted at intervals along the length of the bridge member for displacement between nonoperative parked positions extending along the length of said member and operative positions in which said trusses project laterally from the bridge member for supporting a roof covering, and strut means adapted releasably to interconnect said trusses when in the operative position.

For a better understanding of the present invention and to show how the same may be carried into effect reference will now be made, by way of example, to the accompanying drawings in which:

FIGURE 14 is a perspective view in diagrammatic and fragmentary form of one end of the roof structure of the embodiment of FIGURES l to 11.

Referring now to the accompanying drawings, one embodiment of a roof structure of the invention is shown in FIGURES 1 to 11 and 14. As shown in FIGURE 1 the roof structure incorporates a bridge member 1 formed by an elongated box-section steel lattice beam 2 which is preferably rectangular in cross-section. The bridge member 1 also includes four hydraulically operable loadbearing telescopic end-support 'legs 3 formed as multistage piston and cylinder assemblies and arranged one at each of the four vertical end edges of the member 1 in a manner such that the respective longitudinal axes of the end-support legs 3 are parallel to these end edges. The end-support legs 3 are extensible to raise the roof structure to form a shelter, the end-support legs 3 serving as the sole load-bearing supports 4 for the shelter when in the extended state. The parts of the telescopic end-support legs 3 which can be extended furthest outwardly are adapted to bear on a frame 5. This frame 5 may be adjoined at both sides thereof by a floor structure for the shelter, depending on the particular use to which the shelter is to be put. This frame 5, when the piston and cylinder assemblies forming the end-support legs 3 are retracted is arranged to abut the undersurface of the bridge member 1 and may be releasably connected thereto and also to the ends of the end-support legs 3 which are adapted to be extended furthest. Also the frame 5 is preferably stiffened by braces and serves as a vehicle mountable on bogies for transportation.

In the illustrated form of embodiment, five side trusses of the same length as the bridge member 1 are pivotally connected at equal intervals along the length of the steel lattice-beam 2 of the bridge member 1. Each set of five trusses comprises two outermost trusses 6 of unitary construction, two intermediate trusses 7 and an inner truss 8 which trusses are attached to the bridge member 1 so that respective trusses in each set correspond. The trusses 6 to 8 are secured to the steel lattice-beam 2 by pivotal connections 9 which can be locked in the longitudinal direction of the trusses, as indicated diagrammatically in FIGURE 2. The intermediate trusses 7 each have a further pivotal connection 10 located at a distance from the bridge member 1 which corresponds to the spacing of the trusses from one another, and each inner truss 8 also has a pivotal connection 10, and a further intermediate pivotal connection 11 which is located at a distance from the bridge member 1 corresponding to three times the interval between the trusses.

The intermediate pivotal connections in the trusses must be so constructed that in the unfolded operative state the trusses form structural elements which are stable in themselves. I

Strut means such as struts 12 are arranged at intervals between the trusses 6, 7, 8 to extend parallel to the steel lattice-beam 2 of the bridge member 1. These struts 12 are connected by hooks and eyes to the corresponding trusses 6 and 7 or 7 and 8. For the sake of clarity in the drawings only some of the struts in FIGURES l and 2 have been given the reference numeral 12. As shown in FIGURES 2 to 4 canopy parts 13 are hung on the outer sides of the outer trusses 6 and the outer transverse strut 12. These canopy parts 13 can be swung upwards on the trusses 6 or corresponding struts 12, and are particularly desirable in the case of amusement bump car shelters. Auxiliary uprights 14 which take no part in load bearing or static determinations of the building structure, are arranged below the free ends of the outermost trusses 6 to serve as drain pipes for rain gutters arranged at the transverse sides of the roof structure when the latter has been erected. The free ends of the outermost trusses 6 are connected by diagonal wire ropes 15 to the opposite ends of the bridge member 1 in order to provide wind bracing means.

For the sake of clarity, only one of the piston and cylinder assemblies forming the end-support legs 3 will be described and FIGURES 5 and 6 represent two different views of a corner region of the steel lattice-beam.

2 showing the end-support leg 3, that is the hydraulic telescopic piston and cylinder assembly fixed thereto by means of straps 16. In the view shown in FIGURE 5 a part of the outermost truss 6 is also shown connected by the pivotal connections 9 to the steel lattice-beam 2. The part of the telescopic end-support leg 3 which is capable of the furthest outward extension bears on the frame 5 through the intermediary of a ball joint 17. As already indicated, the frame 5. can be releasably connected both to the steel lattice-beam 2 and also to the furthest extensible end of the end-support leg 3. A slide 18 provides a releasable connection between the ball joint 17 and the frame 5 and the ball joint 17 bears on the slide 18. The ball joint 17 conveniently can be wedged to the slide 18 when the latter is inserted. In FIGURE 6 p the slide 18 is shown partly withdrawn. When the slide 18 is completely withdrawn, the extensible parts of the end-support leg 3 can move through braces 20 and 21 of the frame 5 which braces are indicated in broken lines. When the frame 5 is abutting the undersurface of the steel lattice-beam 2, as shown in broken lines in FIGURE 6, as it is required to do for transporting the bridge member 1, the end-support legs 3 can be extended therethrough when the slides 18 are withdrawn. The releasable connection between the steel lattice-beam 2 and the frame 5 during transport can be effected in any appropriate manner.

FIGURE 7 is a view similar to that of FIGURE 6 and shows an end edge of the steel lattice-beam 2 with the end-support leg 3 in an extended state hearing by means of the ball joint 17 and the slide 18 on the frame 5. Also shown in FIGURE 7 are stabilisation stays 22 consisting of hingeably interconnected parts and connected by pivotal connections 19 between the lower end 4 regions of the bridge member 1 and the underlying frame 5. These stay parts are connected to one another by means of central hinged joints 23 which can be locked in position when the end-support leg 3 is completely extended and the stay parts are in vertical alignment with one another in an operative stabilising position.

FIGURE 9 shows diagrammatically the way in which the trusses 6, 7 and 8 are collapsibly folded onto the bridge member 1. When the roof structure forming the shelter is to be dismantled, from an erected operative position in which the trusses project laterally from the bridge member 1 for supporting a roof surface, the struts 12 between the trusses 6, 7 and 8 are removed and then the inner trusses 8 are collapsed against the bridge member 1, by pivoting about the pivotal connections 11, 1t) and 9 in the illustrated manner. The intermediate trusses 7 follow, pivoting about the connections 9 and 10, and finally the outermost trusses 6 are folded onto the bridge member 1 in the longitudinal direction by pivoting about their connections 9, so that they overlie the trusses 7 and 8 which have already been folded-up. In this way all the trusses are displaced into nonoperative parked positions extending along the length of the bridge member 1.

To this end it is necessary that the trusses 6 are at the most the same length as the bridge member 1. If this is not the case a further intermediate pivotal connection must also be provided in the outermost trusses 6. In order to enable all the trusses to be folded about the connections 9 in a direction parallel to the longitudinal direction of the bridge member I, the connections 9 of the outermost trusses 6 must be arranged laterally at a distance a from the steel lattice-beam 2 which distance corresponds to the thickness of the folded-up trusses 7 and 8. Also, the connections 9 of the intermediate trusses 7 must be located at a distance b from the bridge member 1, which distance corresponds to the thickness or Width of the folded-up inner truss 8. As already indicated, the connections 9, 10 and 11 of the trusses 6, 7 and 8 must be so constructed that they can be locked in the longitudinal direction of the trusses.

FIGURES 10 and 11 show a pivotal connection suitable for the connections 9, 10 and 11, shown in use as one of the connections 9 situated between the outermost truss 6 and the bridge member 1. The connection 9 incorporates mating coupling parts 24 and 25, with the coupling part 24 being connected to the steel lattice-beam 2 of the bridge member 1, with a separation a therebetween for reasons which have been previously explained in conjunction with FIGURE 9. The coupling part 25 is shown connected to the outermost truss 6. The mating coupling parts 24 and 25 accommodate and are interconnected by two pins 26 which can be inserted vertically and are spaced apart transversely to the longitudinal direction of the outermost truss 6. At least one of these pins 26 is capable of being removed from the parts 24 and 25. If both pins 26 are inserted, the respective truss is held in stable manner in the longitudinal direction. However, when the trusses are to be folded-up, one of the pins 26 must be removed, whichever one is to be removed depending on the desired pivoting direction. The remaining pin 26 then forms the pivot point of the connection 9. The pivotal connections 10 and 11 in the trusses 7 and 8 are also correspondingly constructed.

FIGURES 12 and 13 show a modified embodiment of the roof structure in use. The steel lattice-beam 2 of the bridge member 1 in this case has only a single end-support leg 3 formed by a hydraulically actuable telescopic piston and cylinder assembly and located at each end of the bridge member 1. The frame 5 can thus be dispensed with, since with having only one telescopic end-support leg 3 at each end of the bridge member 1 it is not absolutely necessary to have an equal-level supporting surface for the end support legs 3. The other constructional features in this embodiment of the roof structure of the invention correspond to the hereiubefore described embodiment.

In order to obtain a shelter having a considerable clear height in at least one portion, with a combination of roof structure as shown in FIGURES 12 and 13, the outer ends of the operatively positioned trusses 6, 7 and 8 are anchored and located above ground at one side of the bridge member 1 on support trestles 27. In this Way, by extending the telescopic end-support legs 3 the respective roof structure can be moved into an inclined position. FIGURE 12 in a diagrammatic side view shows a combination of two roof structures arranged parallel to one another, with the free ends of the trusses not anchored by the trestles 27, abutting one another and thus providing an extended roof area of considerable clear height and width. FIGURE 13 shows a side view of a plurality of roof structures arranged adjacent one another in louvre-like manner.

It is an important feature of the invention that when the roof structure is to be transported, all the components which are required for its erection and which are not connected to the bridge member are arranged within the boxsection steel lattice-beam 2 of the bridge member 1. A pump 28 and a motor such as a diesel engine 29 connected thereto can be used for actuating the hydraulically operable telescopic end-support legs. In order to have these parts available wherever the roof structure is to be erected to provide a shelter, the engine 29 and the pump 28 for the hydraulic telescopic end-support legs are conveniently arranged within the steel lattice-beam 2 of the bridge member 1. FIGURE 14 is a diagrammatic fragmentary view of one end of the steel lattice-beam 2 of the bridge member 1, showing diagrammatically, the hydraulic pump 28 and the diesel engine 29 provided within the beam 2 for driving the end-support legs. In order to save space within the steel lattice-beam 2 which would otherwise be taken up by a tank for hydraulic fluid, two upper longitudinal members 30 and 31 of the steel lattice-beam 2 of the bridge member 1 conveniently are constructed as tanks for the hydraulic fluid.

For erecting the roof structure of the invention to form a shelter, the following procedure is followed:

First of all the bridge member 1 carried on travelling bogies is transported to the place where the shelter is to be erected. For transport purposes, the trusses 6, 7 and 8 are folded into the non-operative parked position and fixed against the steel lattice-beam 2, the telescopic endsupport legs 3 are retracted and the frame 5 is secured to the undersurface of the steel lattice-beam 2. The endsupport legs 3 are also connected, by means of the slides 18, to the frame 5. All the struts 12 and other components such as for example the uprights 14 are stowed away within the steel lattice-beam 2. An awning which can later be stretched over the roof structure to form a roof surface can be wound on to a bar to form a reel on the steel lattice-beam 2.

For unloading the collapsed roof structure from the bogies, the slides 18 are removed from the frame 5 and the end-support legs 3 are then extended through the frame 5, which remains secured to the undersurface of the steel lattice-beam 2 of the bridge member 1 until the lowermost parts of the end-support legs 3 bear on the ground. Further extension of the end-support legs 3 then raises the bridge member 1 and the attached frame 5 until the bogies can be moved away. After the bogies have been removed, the end-support legs 3 are retracted to lower the bridge member 1 until the frame 5 takes up a position which it will occupy when the roof structure is erected to form the shelter. If the ground is completely even, the frame 5 can rest directly on the ground. However, if the ground surface is uneven, it will be necessary to arrange blocks below the frame 5 to ensure the required horizontal position thereof.

When the frame 5 is horizontal, or has been suitably chocked-up, the end-support legs 3 can be further retracted and connected to the frame 5 by insertion of the slides 18. The frame 5 is then released from the steel lattice-beam 2 and the bridge member 1 of the roof structure is lifted by extending the end-support legs 3, which now hear on the frame 5 by means of the slides 18. The bridge member 1 is lifted until an advantageous working height is reached for the unfolding and strutting of the trusses 6, 7, 8 which now follows. At this working height the entire roof structure can be completed including the awning which is to be drawn over it.

When the roof structure has been completed, it is raised in its entirety with the bridge member 1 to the desired shelter height, by means of the end-support legs 3 and the shelter is then ready for use. A fioor can be provided on the ground at both sides of the frame 5, the type of floor depending on the particular use to which the shelter is to be put. It is also possible to arrange the uprights 14 at the free ends of the trusses 6 to act as drain pipes.

A particular advantage of the hereinbefore described roof structure is that it can be assembled at a convenient working height above the ground, so that no ladders, winches or cranes of any kind are required. This safety feature enables the roof structure to be erected to form a shelter with minimum danger to the erectors.

When erecting the roof structure of the embodiment shown in FIGURES 12 and 13, in which the bridge member 1 only has one end-support leg 3 at each end and has no frame 5, it is best to proceed as follows:

The trusses 6, 7, 8 are unfolded from the bridge member 1 whilst the bridge member 1 is still on the bogies. When the roof structure has been completed, the support trestles 27 are arranged under the trusses at one free end thereof and then the completed roof structure is raised by extending the telescopic end-support legs 3, at which point the transport bogies can be removed. In order to bring several roof structures into the positions relative to one another, as shown in FIGURES 12 and 13, it is merely necessary initially to bring the bogies carrying the respective bridge members 1 into the correct posi tions relative to one another before the roof structures are assembled.

It is to be understood that because the bridge member forms the central portion of the roof structure, it is possible quickly to erect the roof structure to form the shelter, by extending the hydraulically operable load hearing end-support legs and pivoting-out and fixing the side trusses. Also when the end-support legs are retracted and the trusses are in the non-operative parked position against the bridge member the entire roof structure can be transported in the form of a bridge on, for example, a vehicle chassis intended for long timber, with which the front vehicle part guides the rear part.

To conclude, a few dimensions can be given in order to illustrate the size of the multipurpose shelter formed by the roof structure of the invention, without thereby limiting the subject of the invention to the sizes indicated. The size of the bridge member 1 will depend mainly on what is permitted by police regulations for road traffic, since the entire bridge member should be transportable on public roads. In an example produced, the width of the bridge member is 2.5 metres and the length about 14.0 metres. The length of the bridge member 1, however, could be increased for example to 20.0 metres, and then more than five trusses could be provided on each side if necessary. The ,height of the bridge member 1 is limited by the permissable loading gauge for railway Wagons,

since the bridge member plus bogie must not exceed the permissable loading gauge height. On the other hand it is also limited by the height of the hydraulic telescopic end-support legs available. "In the example referred to, the bridge member height is about 1.65 metres.

The clear height of the multipurpose shelter produced will depend on the hydraulic telescopic end-support legs which are used, and which can be extended for example to a height of 3.0 metres. The foregoing description of the roof structure shows that the outermost trusses 6 are conveniently of the same length as the bridge member. If the length of the bridge member is 14.0 metres, as

indicated hereinbefore, the erected shelter length amounts to 2 x 14.0 metres+2.5 metres bridge width i.e. over 30.0 metres. The example produced has shown, supported by static calculations, that the two hydraulic end-support legs arranged at each end of the bridge member at a spacing of 2.5 metres and subjected to high pressure are sufiicient to give the shelter formed by the erected roof structure, reliable stability even against strong wind forces.

With the form of embodiment shown in FIGURE 12 it is possible for a parking shelter to be constructed in a simple manner which has a clear height of about 6.00 to 7.00 metres and a clear width between the end-support legs 3 of about 25 to 30 metres.
